Who discovered potassium-argon dating? Who discovered technetium-99m? Is carbon-14 relative dating? Who discovered analytical chemistry? Who invented fission-track dating? Who discovered americium-241? What is the difference between relative dating and radiometric dating?
Flexible transparent electrodes are in significant demand in applications including solar cells, light-emitting diodes, and touch panels. The combination of high optical transparency and high electrical conductivity, however, sets a stringent requirement
This paper considers the kinematic physical characteristics of ionic beams for maximum relative bio-effectiveness (RBE). RBE studies, based on heterogenous cell survival studies at different laboratories and linear energy transfer (LET) conditions for proton, helium, carbon, neon and argon ions, have...
The algorithm is based on a revised argon collisional–radiative (CR) model that integrates atomic collision processes alongside conventional electron collision processes and radiative transitions. For argon plasma, we adopted atomic data compiled by Vlcˇcˇek for the microwave discharge argon plasma [...
